FOUNTAIN: a modular research platform for integrated real-world evidence generation.

BACKGROUND: Real-world evidence (RWE) plays a key role in regulatory and healthcare decision-making, but the potentially fragmentated nature of generated evidence may limit its utility for clinical decision-making. Heterogeneity and a lack of reproducibility in RWE resulting from inconsistent application of methodologies across data sources should be minimized through harmonization. METHODS: This paper's aim is to describe and reflect upon a multidisciplinary research platform (FOUNTAIN; FinerenOne mUlti-database NeTwork for evidence generAtIoN) with coordinated studies using diverse RWE generation approaches and explore the platform's strengths and limitations. With guidance from an executive advisory committee of multidisciplinary experts and patient representatives, the goal of the FOUNTAIN platform is to harmonize RWE generation across a portfolio of research projects, including research partner collaborations and a common data model (CDM)-based program. FOUNTAIN's overarching objectives as a research platform are to establish long-term collaborations among pharmacoepidemiology research partners and experts and to integrate diverse approaches for RWE generation, including global protocol execution by research partners in local data sources and common protocol execution in multiple data sources through federated data networks, while ensuring harmonization of medical definitions, methodology, and reproducible artifacts across all studies. Specifically, the aim of the multiple studies run within the frame of FOUNTAIN is to provide insight into the real-world utilization, effectiveness, and safety of finerenone across its life-cycle. RESULTS: Currently, the FOUNTAIN platform includes 9 research partner collaborations and 8 CDM-mapped data sources from 7 countries (United States, United Kingdom, China, Japan, The Netherlands, Spain, and Denmark). These databases and research partners were selected after a feasibility fit-for-purpose evaluation. Six multicountry, multidatabase, cohort studies are ongoing to describe patient populations, current standard of care, comorbidity profiles, healthcare resource use, and treatment effectiveness and safety in different patient populations with chronic kidney disease and type 2 diabetes. Strengths and potential limitations of FOUNTAIN are described in the context of valid RWE generation. CONCLUSION: The establishment of the FOUNTAIN platform has allowed harmonized execution of multiple studies, promoting consistency both within individual studies that employ multiple data sources and across all studies run within the platform's framework. FOUNTAIN presents a proposal to efficiently improve the consistency and generalizability of RWE on finerenone.

Comparative Analysis of The Effectiveness of Antihypertensive Therapy Including Spironolactone and Eplerenone in Patients With Essential Hypertension and Atrial Fibrillation.

AIM: To perform a comparative analysis of the efficacy of antihypertensive therapy (AHT) containing spironolactone or eplerenone in patients with essential arterial hypertension (AH) and atrial fibrillation (AF). MATERIAL AND METHODS: The study included 99 male and female patients with essential AH complicated by permanent AF, who were receiving the outpatient treatment at the National Specialized Scientific and Practical Medical Center of Cardiology (Tashkent). The patients aged 61.3±9.5 years, the mean duration of AH was 12.9±8.3 years. All patients were divided into two groups: Group 1, patients who completed a 6-month combination AHT containing spironolactone (n=51); Group 2, patients who completed a 6-month combination AHT containing eplerenone (n=48). AF was diagnosed by electrocardiogram (ECG) and/or 24-hour ECG monitoring according to standard diagnostic criteria. The ECG study was performed in compliance with the American Society of Echocardiography Guidelines in M- and B-modes. The degree of structural vascular alterations was determined by the intima-media thickness of the common carotid artery by duplex scanning and microalbuminuria in morning urine. The concentrations of sex hormones were measured by the enzyme immunoassay. The serum concentrations of lipids, glucose, creatinine, and uric acid were measured by the enzymatic method. The glomerular filtration rate (GFR) was calculated with the EPI formula. Results of all studies were considered statistically significant at p<0.05. RESULTS: The proportion of patients who achieved the target diastolic blood pressure (BP) values was significantly greater in the eplerenone-containing treatment group than in the spironolactone-containing treatment group: 87.8% vs. 67.5% (p=0.043). The proportion of patients who simultaneously achieved the target systolic and diastolic BP values was slightly greater in the eplerenone-containing treatment group than in the spironolactone-containing group (100% vs. 92.1%, p=0.060). The best cardioprotective efficacy was observed in the group of combination AHT containing eplerenone. Specifically, in Group 2, the left ventricular ejection fraction (LVEF) was significantly improved compared to Group 1: from 55.4±10.6% at baseline to 52.6±9.1% in Group 1 (p>0.05) and from 54.8±8.8% at baseline to 58.2±6.4% in Group 2 (p<0.02). Only in Group 2, the left atrial volume index (LAVI) was significantly decreased compared to Group 1. Thus, in Group 1, the LAVI changed from 42.2±15.1 ml/m2 at baseline to 40.4±12.2 ml/m2 (p>0.05) and in Group 2, from 41.2±15.3 ml/m2 at baseline to 37.3±13.5 ml/m2 after the treatment (p<0.05); the ∆% LAVI in the eplerenone group was -5.9% vs. -0.36% in the spironolactone group. In men of Group 1, estradiol significantly increased from 13.9±12.6 pmol/l at baseline to 22.7±12.4 pmol/l (p<0.001). CONCLUSION: The good antihypertensive efficacy of the 6-month combination therapy containing eplerenone was significantly superior to spironolactone in achieving the target BP values. The eplerenone-containing treatment significantly improved LVEF and decreased LAVI compared to the spironolactone-containing treatment. A trend towards a beneficial effect of the AHT containing eplerenone on concentrations of sex hormones was noted in both women and men.

Benefit of combination therapy with dapagliflozin and eplerenone on cardiac function and fibrosis in rats with non-diabetic chronic kidney disease.

Patients with chronic kidney disease (CKD) are at a high risk of cardiovascular (CV) complications. In these patients, sodium-glucose cotransporter-2 inhibitors (SGLT2i) have been shown to reduce CV events. Mineralocorticoid receptor antagonists (MRAs) exert similar benefits in diabetic CKD, though their effects in non-diabetic CKD remain unclear. This study aimed to evaluated whether the combination of Dapagliflozin (DAPA) and Eplerenone (EPLE) would have positive effects on cardiorenal functions in a non-diabetic CKD model. CKD was induced in rats via 5/6 nephrectomy, followed by treatment with DAPA (5 mg/kg/day PO), EPLE (100 mg/kg/day PO) or the combination for 3 months following CKD induction. Cardiorenal functions were assessed after the treatment period. All treated groups showed reduced kidney fibrosis though plasma creatinine and urea levels remained unchanged. Compared to untreated CKD, EPLE or DAPA/EPLE reduced left ventricle (LV) end-diastolic pressure and LV end-diastolic pressure volume relationship, whereas DAPA alone did not achieve significant reductions. Compared to untreated CKD, EPLE and DAPA/EPLE improved cardiac perfusion but DAPA alone did not. Cardiac fibrosis in CKD was blunted by either DAPA or EPLE alone, with the combination showing an additive effect. In conclusion, co-treatment with DAPA and EPLE enhances diastolic function, cardiac perfusion and reduces myocardial fibrosis in non-diabetic CKD rats.

Patiromer Facilitates Angiotensin Inhibitor and Mineralocorticoid Antagonist Therapies in Patients With Heart Failure and Hyperkalemia.

BACKGROUND: Hyperkalemia (HK) is associated with suboptimal renin-angiotensin system (RAS) inhibitor and mineralocorticoid receptor antagonist (MRA) use in heart failure with reduced ejection fraction (HFrEF). OBJECTIVES: This study sought to assess characteristics and RAS inhibitor/MRA use in patients receiving patiromer during the DIAMOND (Patiromer for the Management of Hyperkalemia in Subjects Receiving RAASi Medications for the Treatment of Heart Failure) run-in phase. METHODS: Patients with HFrEF and HK or past HK entered a run-in phase of ≤12 weeks with patiromer-facilitated RAS inhibitor/MRA optimization to achieve ≥50% recommended RAS inhibitor dose, 50 mg/d MRA, and normokalemia. Patients achieving these criteria (randomized group) were compared with the run-in failure group (patients not meeting the randomization criteria). RESULTS: Of 1,038 patients completing the run-in, 878 (84.6%) were randomized and 160 (15.4%) were run-in failures. Overall, 422 (40.7%) had HK entering run-in with a similar frequency in the randomized and run-in failure groups (40.3% vs 42.5%; P = 0.605). From start to the end of run-in, in the randomized group, an increase was observed in target RAS inhibitor and MRA use in patients with HK (RAS inhibitor: 76.8% to 98.6%; MRA: 35.9% to 98.6%) and past HK (RAS inhibitor: 60.5% to 98.1%; MRA: 15.6% to 98.7%). Despite not meeting the randomization criteria, an increase after run-in was observed in the run-in failure group in target RAS inhibitor (52.5% to 70.6%) and MRA use (15.0% to 48.1%). This increase was observed in patients with HK (RAS inhibitor: 51.5% to 64.7%; MRA: 19.1% to 39.7%) and past HK (RAS inhibitor: 53.3% to 75.0%; MRA: 12.0% to 54.3%). CONCLUSIONS: In patients with HFrEF and HK or past HK receiving suboptimal RAS inhibitor/MRA therapy, RAS inhibitor/MRA optimization increased during patiromer-facilitated run-in.

Mineralocorticoid Receptor Blocker Prevents Mineralocorticoid Receptor-Mediated Inflammation by Modulating Transcriptional Activity of Mineralocorticoid Receptor-p65-Signal Transducer and Activator of Transcription 3 Complex.

BACKGROUND: Mineralocorticoid receptor (MR) induces cardiac inflammation cooperatively with nuclear factor-κB and signal transducer and activator of transcription 3 (STAT3); MR blockers exert anti-inflammatory effects. However, the underlying mechanism remains unclear. We investigated the anti-inflammatory effect of esaxerenone, a novel MR blocker, in experimental myocardial infarction (MI) and its underlying mechanisms. METHODS AND RESULTS: Male C57BL/6J mice subjected to ligation of the left anterior descending artery were randomly assigned to either the vehicle or esaxerenone group. Esaxerenone was provided with a regular chow diet. The mice were euthanized at either 4 or 15 days after MI. Cardiac function, fibrosis, and inflammation were evaluated. Esaxerenone significantly improved cardiac function and attenuated cardiac fibrosis at 15 days after MI independently of its antihypertensive effect. Inflammatory cell infiltration, inflammatory-related gene expression, and elevated serum interleukin-6 levels at 4 days after MI were significantly attenuated by esaxerenone. In vitro experiments using mouse macrophage-like cell line RAW264.7 cells demonstrated that esaxerenone- and spironolactone-attenuated lipopolysaccharide-induced interleukin-6 expression without altering the posttranslational modification and nuclear translocation of p65 and STAT3. Immunoprecipitation assays revealed that MR interacted with both p65 and STAT3 and enhanced the p65-STAT3 interaction, leading to a subsequent increase in interleukin-6 promoter activity, which was reversed by esaxerenone. CONCLUSIONS: Esaxerenone ameliorated postinfarct remodeling in experimental MI through its anti-inflammatory properties exerted by modulating the transcriptional activity of the MR-p65-STAT3 complex. These results suggest that the MR-p65-STAT3 complex can be a novel therapeutic target for treating MI.

Role of L-type Ca2+-channels in the vasorelaxing response to finerenone in arteries of human visceral adipose tissue.

Inadequate blood supply to the expanding adipose tissue (AT) is involved in the unhealthy AT remodeling and cardiometabolic consequences of obesity. Because of the pathophysiological role of upregulated mineralocorticoid receptor (MR) signaling in the complications of obesity, this study tested the vasoactive properties of finerenone, a nonsteroidal MR antagonist, in arteries of human AT. Arteries isolated from the visceral AT of obese subjects were studied in a wire myograph. Finerenone resulted in a concentration-dependent relaxation of arteries precontracted with either the thromboxane-A2 analog U46619, ET-1, or high-K+ solution; the steroidal MR antagonist potassium canrenoate, by contrast, did not relax arteries contracted with either U46619 or high-K+ solution. Finerenone-induced relaxation after precontraction with U46619 was greater in the arteries of obese versus nonobese subjects. Mechanistically, the vasorelaxing response to finerenone was not influenced by preincubation with the nitric oxide synthase inhibitor L-NAME or by endothelium removal. Interestingly, finerenone, like the dihydropyridine Ca2+-channel blocker nifedipine, relaxed arteries contracted with the L-type Ca2+-channel agonist Bay K8644. In conclusion, finerenone relaxes arteries of human visceral AT, likely through antagonism of L-type Ca2+ channels. This finding identifies a novel mechanism by which finerenone may improve AT perfusion, hence protecting against the cardiometabolic complications of obesity.

Add-on multidrug treatment based on quadruple therapy successfully treated worsening heart failure caused by anthracycline-induced cardiomyopathy in a survivor of cancer as a young adult: a case report.

BACKGROUND: The overall mortality and morbidity benefit in patients with heart failure with a reduced ejection fraction is greatest with a treatment combination of sacubitril/valsartan, beta-blockers, mineralocorticoid-receptor antagonists, and sodium-glucose transporter-2 inhibitors, termed the "fantastic four" or "quadruple therapy." The addition of vericiguat (an oral soluble guanylate cyclase stimulator) is believed to aid in managing worsening heart failure after quadruple therapy. Among childhood and young adult cancer survivors, cardiovascular complications that develop more than 10 years after anthracycline-based chemotherapy have a poor prognosis. Therefore, this study reports the efficacy of multidrug regimen based on quadruple therapy for worsening heart failure in cancer survivors with anthracycline-induced cardiomyopathy. CASE PRESENTATION: A survivor of cancer as a young adult who received high-dose anthracycline chemotherapy presented with acute decompensated heart failure 20 years post-chemotherapy and worsening heart failure 1.5 years after discharge. The patient showed signs of improvement after a step-wise introduction of carvedilol, empagliflozin, sacubitril/valsartan, ivabradine, and spironolactone for worsening heart failure. Vericiguat was accelerated owing to the risk of more severe cardiovascular events associated with ongoing aortic stenosis and the poor prognosis of anthracycline-induced cardiomyopathy. Heart failure symptoms continued to improve, with significant cardiac reverse remodeling, and the patient successfully underwent aortic valve replacement for severe aortic stenosis. CONCLUSIONS: Our case highlighted that multidrug treatment with add-on vericiguat and ivabradine based on quadruple therapy can potentially treat worsening heart failure in young adult cancer survivors with severe anthracycline-induced cardiomyopathy.

[The 2024 landscape of aldosterone blockade]. / Blocage de l'aldostérone : état des lieux en 2024.

Aldosterone is a steroid hormone playing a key role in arterial hypertension physiopathology. In case of inappropriate secretion, it has a detrimental action on the kidney and cardiovascular system and therefore constitutes an interesting therapeutic target for several diseases. Recent progress allowed to expand the therapeutic arsenal for physician practitioner and new promising drugs will probably appear on the market the next few years. Hence, physicians should know the indications and side effects of these new treatments.

L'aldostérone est une hormone stéroïdienne qui joue un rôle clé dans la physiopathologie de l'hypertension artérielle et l'homéostasie sodique. En cas de sécrétion inappropriée, c'est-à-dire maladaptée à la balance sodique, son action devient néfaste sur le rein et le système cardiovasculaire, ce qui en fait une cible thérapeutique idéale pour de nombreuses pathologies. Des avancées récentes ont permis d'étoffer l'arsenal médicamenteux à disposition du praticien et de nouvelles molécules prometteuses vont probablement faire leur apparition dans les prochaines années. Une bonne connaissance des indications et des effets indésirables de ces traitements est dès lors fondamentale pour tous cliniciens.

Comparative effectiveness and safety of eplerenone and spironolactone in patients with heart failure: a systematic review and meta-analysis.

BACKGROUND: Eplerenone and spironolactone, recognized as mineralocorticoid receptor antagonists (MRAs), have been reported to improve clinical prognosis among individuals diagnosed with heart failure (HF). However, the difference in the clinical effects between eplerenone and spironolactone in individuals with HF remains uncertain. We aimed to assess the impact of eplerenone compared to spironolactone on clinical outcomes within the HF population. METHODS: An extensive search was executed in several databases (PubMed, Web of Science, Scopus, Cochrane Library). All relevant studies evaluating eplerenone compared to spironolactone in patients with HF were included. Dichotomous data were pooled as Hazard ratio (HR) or Risk ratio (RR) with a 95% confidence interval (CI). Our main outcome was all-cause mortality. Secondary outcomes included death from cardiovascular causes, treatment withdrawal, and gynecomastia. RESULTS: Ten studies, comprising 21,930 HF individuals, were included in our investigation. Eplerenone showed a lower risk of all-cause mortality (HR = 0.78, 95%CI [0.64 to 0.94], P = 0.009) and cardiovascular mortality (HR = 0.54, 95%CI [0.39, 0.74], P = 0.0001) compared to spironolactone. Furthermore, eplerenone exhibited a reduced risk of treatment withdrawal (RR = 0.69, 95% CI [0.62, 0.78], P = 0.0001) and gynecomastia (RR = 0.07, 95% CI [0.02 to 0.31], P = 0.0001) than spironolactone. CONCLUSION: Eplerenone revealed lower all-cause and cardiovascular mortality events in comparison to spironolactone. Moreover, eplerenone was associated with lower gynecomastia and treatment withdrawal events compared to spironolactone. Further well-designed randomized controlled trials are still warranted better to identify the clinical differences between eplerenone and spironolactone.

Fixed-dose Combination of Torsemide and Mineralocorticoid Receptor Antagonists.

The combination of torsemide and spironolactone presents a promising approach to managing conditions such as edema and hypertension. Torsemide, a loop diuretic, enhances diuresis by inhibiting sodium reabsorption in the kidneys, while spironolactone, a potassium-sparing diuretic and mineralocorticoid receptor antagonist (MRA), complements this effect by preventing potassium loss and offering additional cardiovascular benefits. This review examines clinical evidence supporting their combined effectiveness in treating fluid retention and improving outcomes in conditions like heart failure (HF). Given the limited research available, it is essential to carefully evaluate patient-specific factors. However, several side effects necessitate careful patient selection and monitoring. Moreover, optimizing dosing regimens is crucial to ensure the safety and efficacy of torsemide and MRAs in clinical settings.

Abdominal obesity is associated with increased worsening renal function risk in patients with heart failure with preserved ejection fraction.

BACKGROUND: Worsening renal function (WRF) is a frequent comorbidity of heart failure with preserved ejection fraction (HFpEF). However, its relationship with abdominal obesity in terms of HFpEF remains unclear. This study aimed to evaluate the value of waist circumference (WC) and body mass index (BMI) in predicting WRF and examine the correlation between abdominal obesity and the risk of WRF in the HFpEF population. METHODS: Data were obtained from the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist trial. Abdominal obesity was defined as WC ≥ 102 cm for men and ≥ 88 cm for women. WRF was defined as doubling of serum creatinine concentration from baseline. Restricted cubic splines and receiver operating characteristic curves were used to evaluate the value of WC and BMI in predicting WRF. Cumulative incidence curves and cox proportional-hazards models were used to compare patients with and without abdominal obesity. RESULTS: We included 2,806 patients with HFpEF in our study (abdominal obesity, n: 2,065). Although baseline creatinine concentrations did not differ, patients with abdominal obesity had higher concentrations during a median follow-up time of 40.9 months. Unlike BMI, WC exhibited a steady linear association with WRF and was a superior WRF predictor. Patients with abdominal obesity exhibited a higher risk of WRF after multivariable adjustment (hazard ratio: 1.632; 95% confidence interval: 1.015-2.621; P: 0.043). CONCLUSIONS: Abdominal obesity is associated with an increased risk of WRF in the HFpEF population. TRIAL REGISTRATION: URL: https://beta. CLINICALTRIALS: gov . Unique identifier: NCT00094302.

Clinical and cost-effectiveness of spironolactone in treating persistent facial acne in women: SAFA double-blinded RCT.

Background: Acne is common, can cause significant impact on quality of life and is a frequent reason for long-term antibiotic use. Spironolactone has been prescribed for acne in women for many years, but robust evidence is lacking. Objective: To evaluate whether spironolactone is clinically effective and cost-effective in treating acne in women. Design: Pragmatic, parallel, double-blind, randomised superiority trial. Setting: Primary and secondary healthcare and community settings (community and social media advertising). Participants: Women aged 18 years and older with facial acne persisting for at least 6 months, judged to potentially warrant oral antibiotic treatment. Interventions: Participants were randomised 1 : 1, using an independent web-based procedure, to either 50 mg/day spironolactone or matched placebo until week 6, increasing to 100 mg/day spironolactone or matched placebo until week 24. Participants continued usual topical treatment. Main outcome measures: Primary outcome was the adjusted mean difference in Acne-Specific Quality of Life symptom subscale score at 12 weeks. Secondary outcomes included Acne-Specific Quality of Life total and subscales; participant self-assessed improvement; Investigator's Global Assessment; Participant's Global Assessment; satisfaction; adverse effects and cost-effectiveness. Results: Of 1267 women assessed for eligibility, 410 were randomised (201 intervention, 209 control), 342 in the primary analysis (176 intervention, 166 control). Mean age was 29.2 years (standard deviation 7.2) and 7.9% (28/356) were from non-white backgrounds. At baseline, Investigator's Global Assessment classified acne as mild in 46%, moderate in 40% and severe in 13%. At baseline, 82.9% were using topical treatments. Over 95% of participants in both groups tolerated the treatment and increased their dose. Mean baseline Acne-Specific Quality of Life symptom subscale was 13.0 (standard deviation 4.7) across both groups. Mean scores at week 12 were 19.2 (standard deviation 6.1) for spironolactone and 17.8 (standard deviation 5.6) for placebo [difference favouring spironolactone 1.27 (95% confidence interval 0.07 to 2.46) adjusting for baseline variables]. Mean scores at week 24 were 21.2 (standard deviation 5.9) in spironolactone group and 17.4 (standard deviation 5.8) in placebo group [adjusted difference 3.77 (95% confidence interval 2.50 to 5.03) adjusted]. Secondary outcomes also favoured spironolactone at 12 weeks with greater differences at 24 weeks. Participants taking spironolactone were more likely than those taking placebo to report overall acne improvement at 12 weeks {72.2% vs. 67.9% [adjusted odds ratio 1.16 (95% confidence interval 0.70 to 1.91)]} and at 24 weeks {81.9% vs. 63.3% [adjusted odds ratio 2.72 (95% confidence interval 1.50 to 4.93)]}. Investigator's Global Assessment was judged successful at week 12 for 31/201 (18.5%) taking spironolactone and 9/209 (5.6%) taking placebo [adjusted odds ratio 5.18 (95% confidence interval 2.18 to 12.28)]. Satisfaction with treatment improved in 70.6% of participants taking spironolactone compared with 43.1% taking placebo [adjusted odds ratio 3.12 (95% confidence interval 1.80 to 5.41)]. Adverse reactions were similar between groups, but headaches were reported more commonly on spironolactone (20.4% vs. 12.0%). No serious adverse reactions were reported. Taking account for missing data through multiple imputation gave an incremental cost per quality-adjusted life-year of £27,879 (adjusted) compared to placebo or £2683 per quality-adjusted life-year compared to oral antibiotics. Conclusions: Spironolactone resulted in better participant-reported and investigator-reported outcomes than placebo, with greater differences at week 24 than week 12.

Acne (or spots) is common and often persists into adulthood. Many people take long courses of antibiotic tablets, but concerns about antibiotic resistance mean alternatives are needed. Spironolactone is a medicine that is sometimes used for acne in women. However, we do not know whether it works. This trial aimed to answer this question. We invited women aged over 18 who had acne on their face for at least 6 months to take part via their general practitioner surgery, hospital or advertising. Women were randomly assigned to two groups: one group was given spironolactone and the other group was given identical-looking placebo ('dummy pill') daily for 24 weeks. Women in both groups could continue using acne treatments applied to the skin (gels/creams/lotions). We asked participants to rate their acne using a questionnaire called Acne-Specific Quality of Life, asked whether they felt their skin had improved and asked skin specialists to assess their skin. Four hundred and ten women took part, many of whom had had acne for a long time. Acne-Specific Quality of Life scores improved in both groups by 12 weeks but improved more in the spironolactone group at 12 and 24 weeks. When asked directly whether their skin had improved, 71% of participants in the spironolactone group said it had, compared with 43% on placebo. Skin specialists were also more likely to report that the acne had improved in the spironolactone group. Side effects were mild and similar in both groups but there were slightly more headaches on spironolactone (20% compared with 12%). Spironolactone is likely to represent value for money for the National Health Service, though this depends on a number of factors including what it is compared to. This trial suggests that spironolactone is a useful additional treatment for women with persistent acne.

Use of Guideline-Recommended Heart Failure Drugs in High-, Middle-, and Low-Income Countries: A Systematic Review and Meta-Analysis.

Optimal use of guideline-directed medical therapy (GDMT) can prevent hospitalization and mortality among patients with heart failure (HF). We aimed to assess the prevalence of GDMT use for HF across geographic regions and country-income levels. We systematically reviewed observational studies (published between January 2010 and October 2020) involving patients with HF with reduced ejection fraction. We conducted random-effects meta-analyses to obtain summary estimates. We included 334 studies comprising 1,507,849 patients (31% female). The majority (82%) of studies were from high-income countries, with Europe (45%) and the Americas (33%) being the most represented regions, and Africa (1%) being the least. Overall prevalence of GDMT use was 80% (95% CI 78%-81%) for ß-blockers, 82% (80%-83%) for renin-angiotensin-system inhibitors, and 41% (39%-43%) for mineralocorticoid receptor antagonists. We observed an exponential increase in GDMT use over time after adjusting for country-income levels (p < 0.0001), but significant gaps persist in low- and middle-income countries. Multi-level interventions are needed to address health-system, provider, and patient-level barriers to GDMT use.

Pharmacological and Device-Based Intervention for Preventing Heart Failure After Acute Myocardial Infarction　- A Clinical Review.

In patients with acute myocardial infarction (MI), heart failure (HF) is one of the most common complications that is associated with a significant burden of mortality and healthcare resources. The clinical benefits of key HF drugs, the so-called "4 pillars" or "fantastic 4", namely ß-blockers, mineralocorticoid receptor antagonists, angiotensin receptor-neprilysin inhibitor, and sodium-glucose cotransporter 2 inhibitors, have been established in patients with HF with reduced ejection fraction, whereas the effects of these drugs are not comprehensively appreciated in patients with acute MI. This review summarizes current evidence on pharmacological and device-based interventions for preventing HF after acute MI.

A Trial of Finerenone in a Patient with Primary Aldosteronism.

INTRODUCTION: Primary aldosteronism (PA), a common secondary cause of arterial hypertension, is treated either surgically or pharmacologically with mineralocorticoid receptor antagonists (MRAs). These drugs, while effective, can cause allergic reactions and have side effects, including menstrual cycle disorders in women. Finerenone is a new, highly selective, nonsteroidal MRA with excellent side-effect profile, primarily intended to slow the progression of diabetic kidney disease and improve cardiovascular outcomes in these patients. No data are available so far on its effect on patients with PA. CASE PRESENTATION: A case of a female patient with confirmed primary aldosteronism, in whom adrenal vein sampling failed twice is presented. The patient developed a skin allergic reaction to spironolactone and experienced prolonged vaginal bleedings with eplerenone, which was attributed to the drug's affinity for progesterone receptors. A trial of finerenone was initiated, resulting in mild increase in plasma renin activity and serum potassium, and somewhat control of blood pressure, but far from optimal blood pressure control, normokalemia, or unsuppression of plasma renin activity. CONCLUSION: This case highlights the challenges of managing PA and describes an attempt of treatment with finerenone to which this patient unfortunately did not adequately respond.

The Impact of a Heart Failure Clinic on Clinical Outcomes: Our Experience.

BACKGROUND: Heart failure (HF) is an emerging pandemic associated with increased mortality, recurrent hospitalizations, and reduced quality of life. Guideline-directed medical therapy has been shown to improve outcomes, particularly in patients with HF with reduced ejection fraction (HFrEF). The main goal of HF clinics is optimizing medical therapy. OBJECTIVES: To assess the impact of our HF clinic on medical therapy and clinical outcomes. METHODS: We obtained demographic, echocardiographic, and clinical data of patients listed in our HF clinic during a 4-year period. Medical therapy was evaluated based on patient reports and documented data. Recurrent admissions for HF were documented. RESULTS: A total of 317 patients (74.1% male, median age 66 years, IQR 55-74) were listed in the clinic with a total of 1140 visits. Of these patients, 62.5% had HFrEF, 20.5% presented with mildly reduced ejection fraction, and 17% showed preserved ejection fraction at the time of the first visit. The use of sodium glucose co-transporter 2 inhibitors and mineralocorticoid receptor antagonists was optimized in 92% and 91% of the patients, respectively. In the subgroup of patients with HFrEF, the use of angiotensin-receptor antagonist/neprilysin inhibitor increased from 22.6% to 87.9% (P < 0.001) and SGLT2 inhibitor use increased from 49.2% to 92% (P < 0.001). During the follow-up period (2.2 years, IQR 1.1-3.1), 203 patients (64%) were readmitted to the hospital for HF at least once. The rate of readmissions decreased over time. CONCLUSIONS: An HF clinic plays an important role in optimizing medical therapy and reducing readmissions.

Effectiveness and safety of finerenone in diabetic kidney disease patients: a real-world observational study from China.

AIMS: Finerenone has been approved for treating diabetic kidney disease (DKD) with reducing cardiorenal risk. Real-world data on finerenone treatment for the management of DKD are presently lacking. This study aimed to investigate the effect of finerenone on the renal parameters of the Chinese DKD population in the real-world medical setting for the first time, especially in combination with renin-angiotensin system inhibitors (RASi) and sodium-glucose cotransporter 2 inhibitors (SGLT2i). METHODS: Forty-two DKD patients were selected and completed a 6-month finerenone treatment. Renal parameters and adverse effects were collected at every visit. RESULTS: The median urine albumin-to-creatinine ratio (UACR) was 1426.11 (755.42, 3638.23) mg/g. Among them, the proportion of patients with a UACR of 300-5000 mg/g was 76.2%, and the proportion of patients with a UACR of >5000 mg/g was 14.3%. The median estimated glomerular filtration rate (eGFR) was 54.50 (34.16, 81.73) mL/min/1.73 m2. Finerenone decreased the UACR significantly throughout the study period (p < .05). The maximal decline of UACR at month 6 was 73%. Moreover, the proportion of patients with a 30% or greater reduction in UACR was 68.42% in month 6. There was a smaller decline (9-11%) in the eGFR after initiating finerenone (p > .05). One patient each discontinued finerenone due to hyperkalemia (2.4%) and acute kidney injury (2.4%). No patient reported hypotension, breast pain, and gynecomastia. CONCLUSIONS: This study from China first demonstrated finerenone decreased UACR with manageable safety in real-world DKD treatment. A triple regimen of RASi, SGLT2i, and finerenone may be a promising treatment strategy for lowering albuminuria and reducing hyperkalemia risk in advanced DKD patients.

Finerenone in Heart Failure with Mildly Reduced or Preserved Ejection Fraction.

BACKGROUND: Steroidal mineralocorticoid receptor antagonists reduce morbidity and mortality among patients with heart failure and reduced ejection fraction, but their efficacy in those with heart failure and mildly reduced or preserved ejection fraction has not been established. Data regarding the efficacy and safety of the nonsteroidal mineralocorticoid receptor antagonist finerenone in patients with heart failure and mildly reduced or preserved ejection fraction are needed. METHODS: In this international, double-blind trial, we randomly assigned patients with heart failure and a left ventricular ejection fraction of 40% or greater, in a 1:1 ratio, to receive finerenone (at a maximum dose of 20 mg or 40 mg once daily) or matching placebo, in addition to usual therapy. The primary outcome was a composite of total worsening heart failure events (with an event defined as a first or recurrent unplanned hospitalization or urgent visit for heart failure) and death from cardiovascular causes. The components of the primary outcome and safety were also assessed. RESULTS: Over a median follow-up of 32 months, 1083 primary-outcome events occurred in 624 of 3003 patients in the finerenone group, and 1283 primary-outcome events occurred in 719 of 2998 patients in the placebo group (rate ratio, 0.84; 95% confidence interval [CI], 0.74 to 0.95; P = 0.007). The total number of worsening heart failure events was 842 in the finerenone group and 1024 in the placebo group (rate ratio, 0.82; 95% CI, 0.71 to 0.94; P = 0.006). The percentage of patients who died from cardiovascular causes was 8.1% and 8.7%, respectively (hazard ratio, 0.93; 95% CI, 0.78 to 1.11). Finerenone was associated with an increased risk of hyperkalemia and a reduced risk of hypokalemia. CONCLUSIONS: In patients with heart failure and mildly reduced or preserved ejection fraction, finerenone resulted in a significantly lower rate of a composite of total worsening heart failure events and death from cardiovascular causes than placebo.
